Several discrete episodes of failure to resist
aggressive impulses that result in serious assaultive acts or destruction of property. The
degree of aggressiveness expressed during the episodes is grossly out of proportion to any
precipitating psychosocial stressors.

The aggressive episodes are not better accounted for by another mental disorder (e.g.,
Antisocial Personality Disorder, Borderline Personality Disorder, a Psychotic Disorder, a
Manic Episode, Conduct Disorder, or Attention-Deficit/Hyperactivity Disorder) and are not
due to the direct physiological effects of a substance (e.g., a drug of abuse, a
medication) or a general medical condition (e.g., head trauma, Alzheimer's disease).
